altered state of consciousness (ASC)

An altered state of consciousness is a state of consciousness that differs significantly from baseline or
normal consciousness often identified with a brain state that differs
significantly from the brain state at baseline or normal consciousness.
However, it is not the brain state itself that constitutes an ASC. The brain
state is an objective matter, but it should not be equated with an EEG or
MRI reading. Otherwise, we would end up counting such things as sneezing,
coughing, sleeping, being in a coma, thinking of the color red, and being
dead as ASCs. Brain state readings reveal brain activity or inactivity, but
are not a good measure of ASCs. Alpha waves,
for example, have been identified with an ASC, but they usually measure lack
of visual processing and lack of focus, though sometimes they measure a
state known as "the Zone" or "the Flow State." This latter state is
experienced by some athletes and video-game players who go on "auto-pilot."*

The baseline brain state might be best defined by the presence of two
important subjective characteristics: the psychological sense of a self at
the center of one’s perception and a sense that this self is identified with
one’s body. States of consciousness where one loses the sense of identity
with one’s body or with one’s perceptions are definitely ASCs. Such states
may be spontaneously achieved, instigated by such things as trauma, sleep
disturbance, sensory deprivation or sensory overload, neurochemical
imbalance, epileptic seizure, or fever. They may also be induced by social
behavior, such as frenzied dancing or chanting. Finally, they may be induced
by electrically stimulating parts of the brain or by ingesting psychotropic
drugs.

Many think the hypnotic state is an ASC. It
certainly often resembles one, but it is doubtful that it is truly an ASC. A
hypnotized person closely resembles certain amnesiacs who can be primed by
being shown certain words. Later they have no conscious recollection of
having been shown the words but they give evidence of implicit memory of the
words. It is doubtful that amnesia should be considered an ASC.

There is little evidence that ASCs can transport one into a transcendent
realm of higher consciousness or truth, as parapsychologists Charles Tart
and Raymond Moody maintain, but there is ample
evidence that some ASCs bring about extremely pleasant feelings and can
profoundly affect personality. Some religious experiences, for example, are
described as providing a very pleasant sense of divine presence and of the
oneness, interrelatedness, and significance of all things. Drugs such as LSD
and mescaline can induce similar feelings. Some patients suffering from
temporal lobe epilepsy think of their disease as temporal lobe “ecstasy,”
since it leaves them with a feeling of being united with a god (Ramachandran
1998). Michael Persinger, a cognitive neuroscience researcher at Laurentian University in Sudbury, Ontario, Canada, claims that he has induced feeling associated with mysticism and alien abduction by stimulating the frontal lobes with magnetic pulses. I doubt he has done so, however. Dr. Olaf Blanke of Geneva University Hospital in
Switzerland found that electrically stimulating the right angular gyrus
(located at the juncture of the temporal and parietal lobes) triggers
out-of-body experiences.*Pehr
Granqvist of Uppsala University found that exposing the temporal lobes
to weak magnetic fields had no discernable effects. "Two out of the three participants in the Swedish study that reported strong spiritual experiences during the study belonged to the control group, as did 11 out of the 22 who reported subtle experiences."* Persinger argued that the replication failed because the magnetic pulses had not been strong enough or given over a long enough period, which seems absurd given that so many subjects in both the control and experimental groups reported strong or subtle effects.(In a related matter, Dr. Stuart Meloy, an anesthesiologist and pain
specialist in Winston-Salem, North Carolina, was testing his pain-relieving
invention on a patient when he accidentally discovered that by electrically
stimulating a woman’s spinal column he could induce orgasm.)

Are the brain states that elicit the feelings of mysticism in the
religious ecstatic, the epileptic, the one on an “acid” trip, and the one
with electrodes attached to his cranium caused by a god? Perhaps, but if so
there is no way of finding this out. Most likely, however, the mechanisms
that trigger these feelings are completely natural. They may be a pleasant
side effect of some evolutionary adaptation, but as yet we do not know why
such brain states are triggered. And while it is an extremely interesting
discovery that religious experiences can be induced by disease, electrodes,
and by drugs, it hardly seems a compelling reason for believing in a god.
Although it might be a compelling reason for taking drugs, for not seeking
treatment, or for using a transcranial electromagnetic stimulator and hoping
for Orgasmatron results like the Woody Allen character in “Sleeper.” Most
religions identify the ideal state as an ASC: losing one’s body and one’s
self, uniting with some sort of Divine Being, and feeling ecstatic pleasure.
In this sense, to seek an ASC is to seek to kill your sense of self while
enjoying the ultimate orgasm.
